Abstract

A communication receiver system, having: receiving circuit for signals of a serial signal frame where each signal frame includes a heading and a data portion; and processing circuit for the supply of the heading of each of the signal frames a synchronous signal of the signal frame of the frequency and a special signal, where, the synchronous signal frame represents that the effective signal frame has been received and the special signal for generation and use in a group of equalizer coefficient.
